Financials Sector (XLF)
Net interest margin plus credit cycle; steepens with the curve.
Financial Select Sector SPDR (XLF) · Profile updated 2026-05-03
Macro Context
Financials is the S&P 500's second-largest cyclical sector and the most directly geared to the shape of the yield curve. Bank net interest margin (NIM) expands when short rates fall relative to long rates (steepening) and compresses when the curve inverts. From 2022-2024, persistent inversion pressured NIM across the large-cap money-center banks; the steepening that began in 2024 restored margin expansion.
The second driver is the credit cycle. Delinquency rates in commercial real estate (CRE), credit cards, and auto loans are rising from the 2021 lows. Charge-off ratios have normalized at JPM and WFC but are elevated at regional banks with concentrated CRE exposure. KRE (regional banks) is the sharpest indicator: its ratio to SPY is one of the cleanest reads on banking-system stress. The March 2023 SVB/Signature failures drove KRE from $60 to $40 in four weeks; KRE has not fully recovered and continues to trade at a discount to the large caps.
The third driver is capital markets activity. Investment banking fees (M&A, IPO, equity issuance) swing violently with the rate cycle. The 2022-2023 drought priced in zero deal flow; 2024-2025 has seen partial normalization. This skews the large-cap financials (GS, MS) more than the depository banks (JPM, BAC, WFC).
Convex monitors XLF alongside the 2s10s slope (T10Y2Y), HY credit spreads (BAMLH0A0HYM2), and the KRE/SPY ratio. When KRE underperforms by more than 15% over 30 days, CRE stress is typically surfacing in earnings.
